Apart from enforcing Newspeak on us the other favourite tool of the Left is the rewriting of history, and nowhere is this more apparent than in the case of the Cold War.
The accepted version of these events is that the Cold War was entirely the fault of wicked US imperialists. This version is now unquestioned and the generations that have grown up since the Cold War have never been exposed to anything upsetting, such as the truth.
A key component of the liberal version of these events is that the investigations carried out by Senator Joe McCarthy and by the House Un-American Activities Committee were part of a diabolical paranoid conspiracy theory and that there were no Soviet spies in the US in the 1940s and 1950s.
This is a spectacular liberal lie. In spite of frantic attempts by the liberal establishment to destroy key evidence, a process convincingly documented in M. Stanton Evans’ excellent book Blacklisted by History: The Untold Story of Senator Joe McCarthy and His Fight Against America's Enemies, there is now more evidence available on this subject than was the case at the time.
Material from the US Army’s code-breaking Venona project of the 40s was not publicly available until 1995. In addition there have been memoirs by ex-KGB officers, and a number of scholarly works on the murky and unsavoury history of the Left in the United States and the Left’s later attempts to whitewash this history (such as John Earl Haynes and Harvey Klehr's In Denial: Historians, Communism, and Espionage).
It is now clear that the Soviet penetration of the US government and US institutions was in fact more widespread and more serious than even Senator McCarthy imagined. There is also no longer any doubt that people like Alger Hiss and the Rosenbergs were indeed Soviet spies. The execution of the Rosenbergs, far from being an example of wicked persecution of innocent liberals, was entirely justified.
The penetration of the US State Department was on a gigantic scale. There were so many Soviet agents in the State Department that anyone under suspicion could sleep easily knowing that if they were investigated the investigations would almost certainly be carried out by fellow Soviet spies or by reliable communist sympathisers.
McCarthy was neither deluded nor evil. He was a courageous patriot whose memory has been shamefully blackened by liberals. Sadly even most conservatives today do not recognise that McCarthy was right. And the situation today is far worse than it was in McCarthy’s day.
